currently active in the master. The ActiveSlave will continuously loop from 1
to NumberOfSlaves, when the driver is active.

ActiveSlave is the index number, which does not
necessarily have any relationship with the actual slave Profibus address.

PD
667 hardware not detected
|
If MasterStatus is not = 0, an error is detected and the
driver is halted. There will be no activity on the Profibus network. Checking
is only done when loading the driver. When the data is corrected the driver
must be reinitialized setting ReStartDriver to true or by Reset or Power cycle.
ScanCounter
|
|
ScanCounter:
|
Word;
|
(0..10000)
|
ScanCounter is incremented by one each time a full scan of
all slaves has been performed.
The ScanCounter counts to 10000, and then it restarts from
1.
Version
Version shows the version number of the Profibus driver.
Example:
'Version 1.09' is shown as '109'
ReStartDriver
If the driver is halted at startup, due to detected
illegal parameters (MasterStatus > 0), the ReStartDriver flag can be set
and the PD 667 will reset and make a new start.
InitCounter
Counts the number of times the driver has been
initialized.
